getinfo.m

信号实验常用的simulink模型和mfile,可直接在matlan下运行。

function HelpInfoStr=getinfo(editHndl,partNum);
% GETINFO Get help information about SnS items
%         Separators:
%           [part] - Identifies different items' help information;
%           [n]    - Puts 'next line' in help information of a item. 

infoMat=get(editHndl,'UserData');
rowNum=size(infoMat,1);
j=0;
infoStr='';

for i=1:rowNum,
   lineStr=deblank(infoMat(i,:));
